During this past ice storm, my wiper wasnt the only thing that got torn up. (driver side does not turn now)

But my driver head light gasket has cracked and torn apart and now it flaps around when driving. Question is: Do i need to order another set of gaskets or is there another fix for this? I know I am not the only one that has/had this problem, but I can not locate their posts.

How do I fix this?
